TUCSON, Ariz. (AP) - Gabe York scored 13 points and Dusan Ristic added 12, providing No. 7 Arizona an unexpected lift in a difficult 57-47 victory over UCLA on Saturday night. Arizona (24-3, 11-2 Pac-12) was abysmal offensively to start both halves and allowed UCLA to rally from a 14-point halftime deficit. Ristic and York helped Arizona out of its first-half funk, combining for 22 of Arizona's 32 points. T.J.

UCLA played as if it had something to prove at the start, hounding Arizona's ballhandlers and forcing tough shots. The Wildcats missed their first eight shots and had four turnovers in their opening nine possessions, looking like a nervous road team, not the nation's seventh-ranked team playing at home. A pair of backups finally got Arizona going. Ristic hit two free throws at 13:55 for Arizona's first points, then popped in consecutive jump hooks. York hit a couple of 3-pointers off the bench and added another a couple minutes later. Ristic had 12 points and York 10 to help Arizona build a
